Interesting enough this word entered even the German language. At least for Northern Germany an Berlin 'Meine Buxen' in colloquial is used for 'my trousers'. (However in High German 'Buchse' would refer to an electrical inlet)
'Trousers' is UK English for 'Bukser'. 'Pants' eller 'underwear' in UK English for 'Undertøj'
'Pants' is American English for 'Bukser'. 'Underpants' is American English for 'Undertøj'. Hope this helps!!
i answered this as 'my trousers' just now and it told me i was wrong. My Danish dictionary defines 'bukser'as 'trousers'. This is obviously written in American English. I'll remember next time but i lost a life despite being correct.
